I figure if it comes to that, my own efforts will take place among about 4 light trucks of the pickup/CUKVEE class, carrying pretty close to what an ACAV M113 did back then [a .50, a pair of M60s, plus other novelties.
But by the time your basic load of ammo and POL are expended, I'd also expect you to have picked up more than a few usable replacements and ammo thereof from those in opposition to your efforts. And if hosed in the process, then you'll have no further concerns for such Earthly matters and material.
